Description

UNITED STATES PATENT OFFICE. k
EDWARD HOIT NUTTEB, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR T MINERALS SEPARATION AMERICAN SYNDICATE (1913) LIMITED, OF LONDON, ENGLAND.
CONCENTRATION OF ORE.
No Drawing.
To all whom it may concern:
Be it known that I, EDWARD HOIT TER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in the Concentration of Qres, of which the following is a specification.
This invention is for improvements in or relating to ore concentration and relates more particularly to the processes of the type generally known as the froth flotation processes.
The invention is in some respects a development from that covered in the United States Patent No. 962,678.
It has been found that there are a number of hydrocarbons, particularly unsaturated hydrocarbons, which when treated with sulfuric acid form compounds very suitable for use as frothing agents in the froth flotation processes of ore concentration and with some ores these agents have advantages in forming a cleaner concentrate or a'inore stable froth. These products are obtained in the treatment and refining of hydrocarbons, such as petroleum, kerosene, gas-tar and the like, and particularly in the refining of their distillates. A typical example of such products is known as acid sludge, and it has been found, for example, that acid sludge produced by the sulfuric acid treatment of kerosene obtained from California petroleum is highly advantageous as a frothing agent.
In the employment of the agitation froth process as described for example in the United States Patents Nos. 835,120 and 962,678, difliculties are frequently encountered when the ore pulp contains very fine angue slimes or colloidal gangue slimes. This is frequently the case for example with 'copper ores and the-use of the compounds produced by the action of sulfuric acid on hydrocarbons of the type descr bed has provedv especially advantageous in such cases. Excellent results have been obtained for example by using these frothing agents a in the sub-aeration process of ore concentration as described for example in the United States Patents Nos. 1,155,836 and 1,155,815.
The following is an example of the operation of this rocess. The material operated was the taihngs from water concentration tables in the treatment of copper ore from Specification of Letters Patent.
Application filed August 31, 1915. Serial No. 48,169.
Patented Feb. 8, 1916.
the Anaconda mines, Montana, and these tailingsassayed 2.26% of the copper. .To a pulp containing this material in the proportion of 24.0% of solids, was added 2.3 lbs. acid sludge per ton of material treated, 2.3 lbs. wood creosote per ton of material treated, .21 lbs. stove oil per ton of material treated, 12.7 lbs. sulfuric acid per ton of ore. The pulp heated to 97 Fahrenheit was treated in a standard mineral separation fiotation machine wherein it was agitated to form a froth and the froth was separated. The concentrates assayed 10.1% copper and the tailings assayed .2% copper. It is further found that these substances producedby the action of sulfuric acid on hydrocarbons are, in many cases, more effective as frothing agents when they have been standing for some time, or when they have been mixed with water for some time, and this invention includes the use of such compounds in these conditions.
This invention may be used in conjunction with any of the known or patented processes of ore concentration by froth flotation, either for the separation of the metalliferous constituents of an ore from the gangue, or forthe separation of different metalliferous constituents from one another.
